SOFT-TREAD HORSESHOE.

SPEGIFIGATIQN forming part of Letters Patent No. 699,373, dated May 6,1902. Application filed January 5, 1900. Renewed July 3, 1901. SerialNo. 67,007. (No model.)

To all whom, it may concern:

Be it known that I, ORION E. DYsON, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Horseshoes, of which the following is a specification.

This invention relates to horseshoes, and has for its object to providea construction whereby slipping will be prevented, while at the sametime the evils resulting from the jarring contact of the shoe with theroadway may be avoided.

To these ends my invention consists in certain novel features which -Iwill now proceed to describe and will then particularly point out'in theclaims.

In the accompanying drawings, illustrating the preferred embodiment ofthe invention, Figure l is a plan view of the under side of a horseshoeembodying my invention. Fig. 2 is a detail sectional view taken on theline 2 2 of Fig. 1, and Fig. 3 is a detail sectional view taken on theline 3 3 of Fig. 1.

In the said drawings, 1 indicates the body of the shoe, which isconstructed of metal in the usual manner and,which is thickened on theunder side at each heel portion and recessed at the thickened portion,as indicated at 2, thus forming a socket surrounded by thedownwardly-extending flange 3. The front portion of the flange, whichextends transversely of the shoe, is preferably straight. The lateralportions, which follow the margins of the shoe, are curved to correspondto the curvature of the shoe, while the rear portion of the flange ispreferably rounded, as shown. This rear portion is undercut, asindicatedat 4, and the extreme end of the heel of the shoe is beveled in acorresponding manner, as indicated at 5. The front wall of the recess 2is inclined in the same direction as the undercut rear wall 4, thisinclination being shown at 6 in Fig. 2 of the drawings.

Vithin each of the recesses or sockets 2 there are located two pins orstuds 7, which extend some little distance downward from the horizontalwall of the recess, as indicated in Fig. 2. These studs may be eitherseparate pieces secured in position in any suitable manner or they maybe formed integral with the shoe, as desired. In conjunction with thesestuds I employ tread portions in the form of rubber pads or cushions S,which are provided with coils 9, of spring-wire, adapted to lit andgrip-the studs 7. In my preferred construction the two coils are made ofa single piece of wire connected by an intermediate portion 10, and thewinding of the two coils is reverse. I prefer to embed these coils inthe rubber cushion previous to the vulcanization of this latter, so thatsaid coils become firmly connected with the rubber cushion and arepractically integral therewith. The distance between the coils is ofcourse such as to cause them to properly fit over the studs 7. Theheel-cushions 8 are shaped to conform to the shape of the recesses orsockets 2 in which they fit, the rear end of each cushion being beveledor inclined, as shown at 11, to fit underneath the undercut portion atof the retaining-flange, while the front portion of the cushion isundercut, as indicated at 12, to fit the beveled or inclined portion (3of the wall of the recess or socket. The front end of each rear cushionbelow the beveled portion 12 is rounded off, as indicated at 13. I alsomay provide the shoe with a toe-cushion 14, also construct-ed of rubberand held in a channel 15, between the ordinary metallic toecalk 16 ofthe shoe and a rear flange 17, the inner face of the flange and theupper portion of the calk being beveled, as shown, and

the cushion 14. being correspondingly beveled to fit in the channel 15thus formed. This channel is provided with two studs 7 in the manneralready described, while the cushion:

tread portion 14. is provided with coils 9, connected by a cross piece10, identical with those employed in the heel-cushion.

It will be seen that the elastic pads form a cushion for the foot of thehorse, which avoids to a great extent the evils arising from the jarringand concussion of the ordinary metal shoe on the roadway. It will alsobe observed that the frictional adhesion of the rubber will almostentirely prevent any slipping of the animal upon the surface of theroadway. The pads or cushions may be readily applied by forcing thestuds or pins 7 into the hollow interiors of the coils 9, which latterwill yield to receive the studs and will grip them so tightly as toprevent accidental withdrawal or displacement of the cushions. 1 Thefree ends of the studs are preferably somewhat reduced or tapered inorder to facilitate their introduction into the interior of the coils.Owing to the fact that the coils are connected by the intermediate piece10, they are certain sockets.

to be located at the proper distance apart, while the said intermediateportion strengthens the structure. and removes a portion of the strainupon the rubber of the pad or cushion. The coiling of the two coils inopposite directions and the connecting of them by the intermediate pieceserve to more firmly retain the pad in place on the pins, for the reasonthat any tilting or lifting of one end of the pad will serve to tightenthe coil at the other end around its pin through the medium of theconnecting-piece. The pads are further held in place by the surroundingflanges, which tend'to prevent lateral displacement of the pads,'and inthe case of the heel-pads longitudinal displacement, which is liable toarise from the nature of the strains to which these pads are subjected,is also prevented by the flanges. These heel-pads are additionally heldin place by means of the undercut flanges 4, while the beveling orslanting of the rear portion of the pad and shoe at these points servesto prevent excessive wear of the pad and brings the metal of the shoeinto contact with the ground when the front end of the shoe is tiltedupward much earlier thanwould be the case if the rear ends of the shoeand pad were vertical. The rounding of the front portions of theheel-pads permits them to engage the ground with less longitudinalstrain upon the pads than if these front ends were vertical or angular.While the pads are firmly held in position by the grip of the coils uponthe pins under the conditions of use, said pads may be readily removedby inserting under them a suitable implement and prying them outwardfrom their This arises from the fact that pressure applied to the coilsat the end nearest the shoe tends to release their grip upon the pins,while any pulling strain, such as arises from contact with the ground,tends to tighten other material may be used without departing from thespirit of the invention. While the beveling of the heel of the shoe andthe particular shape given to the projecting portions of the heel-padsare preferred by me for the reasons already given, they form no part ofmy present invention and may therefore be modified or dispensed with.Other modifications will readily suggest themselves, and I therefore donot wish to be understood as limiting myself to the precise details ofcon struetion hereinbefore set forth, and shown in the accompanyingdrawings.

I claim 1. The combination, with a horseshoe having a projecting stud,of a pad or cushion of rubber or other elastic material, and a coil ofspring-Wire embedded in the pad or cushion and adapted to receive andgrip the stud, substantially as described.

2. The combination, with a horseshoe having a seat or recess and a studor pin projecting into the same, of a pad or cushion of rubber or otherelastic material adapted to fit said recess, and a coil of wire embeddedin said pad and adapted to receive and grip said stud, substantially asdescribed.

3. The combination, with a horseshoe having a pair of studs projectingtherefrom, of a pad or cushion of rubber or the like, and a wire benttoform two coils and an intermediate connecting portion and embedded inthe pad or cushion, said coils being adapted to receive and grip thestuds, substantially as described.

1 4. The combination, with a horseshoe having two projecting studs, of apad of rubber or the like, and a wire bent to form twooppositely-twisted coils and an intermediate connecting portion andembedded in the pad or cushion, said coils being adapted to receive andgrip the studs, substantially as described.

5. The combination, with a horseshoe having a socket or recess and studsprojecting into the same, of a pad or cushion of rubber or the likeadapted to fit said socket or recess, and a wire bent to form twooppositelytwisted coils and an intermediate connecting portion andembedded in the pad or cushion, said coils being adapted to receive andgrip the studs, substantially as described.
